The main function of automobile hub is to bear load and provide precise guidance for hub rotation. It bears both axial load and radial load. It is a very important component. The use scope and quantity of hub bearing unit are increasing day by day. Now it has developed to the third 

generation. The third generation hub bearing unit adopts the combination of bearing unit and ABS anti-lock braking system. The hub unit is designed with inner flange and outer flange. The inner flange is fixed on the drive shaft with bolts, and the outer flange is used to install the whole bearing together. Nowadays, most automotive parts manufacturers are exposed to the processing of bolt holes on flanges. Their processes are different and their efficiency varies greatly.

At the beginning of 2017, a well-known automobile hub bearing company, whose product order volume has increased sharply, according to the current parts processing technology, the production capacity can not meet the order volume. Afterwards, the Blake cutter approached it and finally gave a mature plan.
Former customer's tool processing technology: drilling D10.6 hole chamfering (aperture +/-0.02). However, the product quality is generally unstable, mainly concentrated in the drift of aperture, entrance chamfering burrs, scratches on the surface of parts caused great confusion to customers.

Tool technology provided by Fulake: a D10.6*90 degree compound drill to eliminate improvement problems.

In four days, the design, production and coating of Fulake cutter are delivered to customers for trial. Customers are quite satisfied with the trial effect, which is in line with the accuracy and life stability. According to the results of customer feedback, now a drill is in place directly, which greatly reduces the processing time and improves the efficiency by 200%.
The drill technology designed by Fulake achieves the following five points:
1. Aperture Guarantee +/-0.02 Tolerance
2. The chamfer surface is smooth, without knife lines and flanging burrs.
3. Improving chip breaking effect, no scratches on parts surface
4. Extending the edge of the sub-groove and increasing the grinding times
5. Optimizing process rhythm, reducing cost and improving efficiency
